Mike, if I’m understanding you correctly, that shouldn’t need replacing… and is usually steel…If it isn’t exposed enough, they can be pulled out a little more with a pair of vise grips or a metal vise…If it’s exposed too much, you can tap it in a little further by tapping the point on the metal vise and re-sharpening it…You just don’t want to push-pull them, back and forth, too much or they’ll be too loose…If that happens it will need replacing with something of similar shape, only a little bigger…Hope this helps…Oh, I forgot to mention… if it’s not exposed at all, or not enough for you to grab, they usually go right through anyway… meaning, you should be able to take a tiny brad and tap it out a little from the back side…

well mike if you want to change the brad…it will depend on what you want to change it to..you could change it to a frank or a tom or a harry or maybe even a charlie…but other then that..i dont know how else to change a brad….LOL…now i hope your laughing at that one…if not…dont be so cranky…hey you could change the brad to cranky…...ok…maybe it was all a bad joke…or maybe not…lol….......did it work…grizz
